Struct BaselineAggregator

pkg/traceql/engine_metrics_compare.go:352–361

BaselineAggregator is a special series combiner for the compare() function. It resplits job-level results into baseline and selection buffers, and if an attribute reached max cardinality at the job-level, it will be marked as such at the query-level.

// an attribute reached max cardinality at the job-level, it will be marked
// as such at the query-level.
